Description

Anordning ved elektriske maskiner med væskekjølede rotorviklinger, og fremgangsmåte til fremstilling av slike viklinger. Device for electric machines with liquid-cooled rotor windings, and method for producing such windings.

Ved elektriske maskiner med likestrcJmmagnetiserte utpregede rotorpoler og utfcirt for stor effekt, altså særlig store synkronmas-kiner, f.eks. vekselstrbmgeneratorer drevet av vannturbiner, anvender man for magnetiseringsviklingene regelmessig ledere med flatt tverrsnitt og viklet på hOykant, dels, i tilfellet av luftkJtJling, for å få kjblet de enkélte vindinger best mulig, og dels av hensyn til spolenes mekaniske fasthet, idet vindingene får stort motstandsmoment overfor sentrifugal-kraften» komponent loddrett på polaksen, noe som ved luftkjblede viklinger er av særlig betydning fordi det er viktig at polmellomrommene minst mulig opptas av viklingsstOtter som stenger for kJBleluftstrOmningen. In the case of electrical machines with direct current magnetized pronounced rotor poles and designed for high power, i.e. particularly large synchronous machines, e.g. alternating current generators driven by water turbines, conductors with a flat cross-section and wound vertically are regularly used for the magnetization windings, partly, in the case of air cooling, to get the individual windings wired as well as possible, and partly out of consideration for the mechanical strength of the coils, as the windings have a large resistance moment against the centrifugal force" component perpendicular to the pole axis, which is of particular importance in the case of air-coupled windings because it is important that the spaces between the poles are occupied as little as possible by winding supports that block the cable air flow.

Det er imidlertid også kjent å kJOle rotorviklingene med vaske, særlig vann. Man har her også stadig benyttet hOykantvlklede ledere, og kjblingen har vært ordnet på den måte at man enten har benyttet hule ledere eller et særskilt væskelednlngssystem som er fbrt langsetter ledervindlngene for å fOre bort varmen fra disse. Por ikke å få for store vanskeligheter med avtetning og isolasjon av inn- og uttak for væske er det i den forbindelse bnskelig å ha flest mulig vindinger i serie på vannsiden, noe som betinger et forholdsvis stort tverrsnitt av kjblekanalen i og med at den tillatte vannhastighet er be-grenset, særlig i tilfellet av vannfbrende ledere, hvor hastigheten av hensyn til faren for tæring på kobberet iallfall ikke vesentlig bbr overstige 1,5 m/sek. På den annen side er også elektrisk seriekobling av samtlige vindinger bnskelig for å holde den tilfbrte magnetiseringsstrbm på et rimelig nivå, noe som betinger lave og flate ledertverrsnitt og l dermed en tilsvarende lav tverrsnittsform av kjblekanalen. However, it is also known to cool the rotor windings with washing, especially water. High-angle conductors have also always been used here, and the wiring has been arranged in such a way that either hollow conductors have been used or a special liquid conduction system that has been made to extend the conductor windings to remove the heat from them. In order not to have too great difficulties with sealing and isolating the inlet and outlet for liquid, it is therefore desirable to have as many windings as possible in series on the water side, which requires a relatively large cross-section of the cable channel in that the permitted water velocity is limited, particularly in the case of water-conducting conductors, where the speed should in any case not significantly exceed 1.5 m/sec due to the risk of corrosion of the copper. On the other hand, electrical series connection of all windings is also desirable in order to keep the applied magnetizing current at a reasonable level, which requires low and flat conductor cross-sections and thus a correspondingly low cross-sectional shape of the cable channel.

QJbres selve lederen hul, medfbrer dette en betydelig fordyrelse, dels fordi hule kobberskinner faller langt dyrere enn massive ledere, og dels fordi de bare kan leveres i forholdsvis små lengder så ! viklingene må skjbtes i korte avstander og hver skjbt må utfbres nbyaktig ^ og kontrolleres omhyggelig» If the conductor itself is made hollow, this leads to a significant increase in price, partly because hollow copper rails are far more expensive than solid conductors, and partly because they can only be supplied in relatively small lengths so ! the windings must be worked at short distances and each work must be carried out precisely ^ and carefully controlled"

På den annen side har man ved de hittil foreslåtte I systemer for vannkjbling av seriekoblede ledervindinger ved maskiner ; med utpregede poler ved hjelp av særskilte rbr for det meste vært nbdt . j til å isolere rbrene mot lederne, noe som gir dårligere varmeovergang, ! On the other hand, with the systems proposed so far for water coupling of series-connected conductor windings in machines; with pronounced poles by means of special rbr mostly been nbdt. j to insulate the wires against the conductors, which results in poorer heat transfer, !

Den foreliggende oppfinnelse tar sikte på å realisere i en væskekjbling, særlig vannkjbling, av- rotorviklingene på ca enklere, j billigere og i det hele tatt mere hensiktsmessig måte og går i fbrste rekke ut på at rotorspolenes vindinger ér viklet på lavkant, og at der j langs kanten av og i god varmekontakt med vindingene er anordnet et væskelednlngssystem. The present invention aims to realize in a liquid coil, especially water coil, the rotor windings in an approximately simpler, cheaper and altogether more appropriate way and primarily assumes that the windings of the rotor coils are wound on a low edge, and that there j along the edge of and in good thermal contact with the windings, a fluid conduction system is arranged.

At dette finnes forsvarlig, beror på erkjennelsen av at der ved et væskekjblet system 1 virkeligheten elett Ikke er behov for å ha vindingene på hbykant av hensyn til kjblingen, og der heller Ikke cr noe i veien for å fylle opp polmellomrommene i tilstrekkelig grad til å avstbtte de lavkantviklede spoler mekanisk når luftkjblingen er erstattet méd væskekjbling. I Ved den nye fmordning får man en ganske annen frihet 1 dimensjoneringen åv ledertvertsnittene bg i disposisjonen av spoler og vjBSkeledninger. Således kan viklingene bygges opp i et bnaket antall lag av seriekoblede vindinger, som blir billigere å vikle fordi de ligger på llavkant, og som kan kjbles med et lednings sys tem langs den ene ellar bagge kanter av vindingene i hvert lag så man ikke får vanskeligheter med tetning og isolasjon. Benyttes et s»rskilt rbrsystem, kai man til dette benytte et billig, f.eks. kvadratisk profil i direkte metallisk forbindelse med ledervindingene uten mellomliggende isolasjon, så der fås god varmekontakt, samtidig som man for rbrene kan benytte et materiale, f.eks. en kobberlegering, som tillater en relativt hby vannhastighet av 2,5 - 3 m/sek uten fare for erosjon. That this is found justifiable is based on the recognition that with a liquid-wired system 1 there is in reality no need to have the windings on the edge for reasons of the wiring, and there is also nothing in the way of filling up the inter-pole spaces to a sufficient extent to the low edge wound coils are mechanically dusted when the air coupling is replaced with liquid coupling. With the new arrangement, you get quite a different degree of freedom in the dimensioning of the conductor cross-sections bg in the arrangement of coils and power cables. In this way, the windings can be built up in a fixed number of layers of series-connected windings, which are cheaper to wind because they are on the lower edge, and which can be wired with a wiring system along one or both edges of the windings in each layer so that there are no difficulties with sealing and insulation. If a separate cable system is used, use a cheap one, e.g. square profile in direct metallic connection with the conductor windings without intermediate insulation, so good thermal contact is achieved, while a material can be used for the wires, e.g. a copper alloy, which allows a relatively high water speed of 2.5 - 3 m/sec without risk of erosion.

Samtidig med at alle lag av viklingen kobles i serie elektrisk, kan også alle rbrvindinger i samme lag kobles i serie hydraulisk, mens kjbleledningene for forskjellige lag kan kobles i serie eller parallelt alt etter hva som passer. De anvendte rOr kan fås i slike lengder at det vil klare seg med et fåtall skjoter pr. lag. At the same time that all layers of the winding are connected in series electrically, all tube windings in the same layer can also be connected in series hydraulically, while the cables for different layers can be connected in series or parallel depending on what suits. The pipes used can be obtained in such lengths that it will be possible with a few joints per layer.

En viktig fordel når lederen vikles på lavkant, ligger An important advantage when the conductor is wound on a shallow edge is

i at det er mulig å forbinde rOret med lederen fOr oppviklingen, f.eks. in that it is possible to connect the tube with the conductor before winding, e.g.

■ : Ti'' ■ : Ten''

ved slaglodding, og vikle opp leder og rbriii fellesskap. I den forbindelse er det også gunstig at slagloddingen av rbret til lederen ikke blir kritisk, idet dens hovedoppgave er å sbrge for god varmekontakt mellom rbr og leder, og denne kontakt vil bli sikkert vedlikeholdt under drift fordi sentrifugalkraftens komponent parallelt med polaksen til enhver tid vil bidra til å presse rbr og ledei* tett sammen. - Imidlertid lar det seg også gjbre, istedenfor å vikle kjblerbr langsetter spolenes enkelte vindinger, å benytte flate kjblelegemer som er utformet med væskekanaler, og sira anbringes isolert mellom de enkelte lag av spolene og dekker hele disses radiale bredde, idet der stadig på grunn av anleggstrykket, som holdes sikkert vedlike av sentri-fugalkraften, og oppdelingen'av spolen i. lag med mellomliggende kjblelegois? kan oppnås en tilfredsstillende varaebortfbring fra de enkelte vindinger. by brazing, and winding up conductor and rbriii joint. In this connection, it is also beneficial that the brazing of the tube to the conductor does not become critical, as its main task is to ensure good thermal contact between tube and conductor, and this contact will be safely maintained during operation because the component of the centrifugal force parallel to the pole axis will at all times help to press rbr and ledei* tightly together. - However, it is also possible, instead of winding cables along the individual turns of the coils, to use flat cable bodies that are designed with liquid channels, and the sira is placed in isolation between the individual layers of the coils and covers their entire radial width, as there is constantly due to the installation pressure, which is maintained securely by the centrifugal force, and the division of the coil into layers of intermediate carbon alloys? a satisfactory product removal from the individual windings can be achieved.

Forbvrig vil man selv i tilfellet av at man ikke be-nytter egne rbr for væskeledningssystemet, kunne nyttiggjore seg flere av de anfOrte fordeler ved oppfinnelsen ved at man, idet man går ut fra et vanlig rektangulært kobberprofil, i kanten i av. lederen freser et spor som tildekkes med ét passende kobberprofil som sveises eller slagloddes til lederen fbr omviklingen. , ! Furthermore, even in the event that you do not use your own pipes for the fluid line system, you will be able to make use of several of the listed advantages of the invention by starting from a normal rectangular copper profile, at the edge of the conductor mills a groove which is covered with a suitable copper profile which is welded or brazed to the conductor for wrapping. , !

I En hensiktsmessig utfbrelsésform av anordningen ifblge oppfinnelsen erj anskueliggjort på tegningen, som viser de til hinannen I stbtende områdér av to rotorpoler' sett aksialt til maskinen og med viklingen »på den ene gjennomskåret. i Viklingene 1, 1 på dé to poler 2, 2 er avstbttet mot' ' hverandre ved mellomliggende viklihgsstbtter 3, som på grunn av vann-kjblingen gjerne kan dekke det vesentlige av polmellomrommet for effektivt å avstotte viklingene, sorn vist utfbrt i tre lag av seriekoblede vindinger 4 med rektangulært profil og viklet utenom hverandre på lavkant. Langs den ene kant av vindingene strekker der seg vannkjblings-rbr 5 med firkantprofil i god varmekontakt med de respektive vindinger og isolert mot det tilstbtende vlndingslag. Elektrisk og hydraulisk til-knytning kan hensiktsmessig skje ved enden av maskinen som antydet for polen til venstre på figuren. A suitable embodiment of the device according to the invention is illustrated in the drawing, which shows the adjacent regions of two rotor poles seen axially to the machine and with the winding on one section cut through. in the windings 1, 1 on the two poles 2, 2 are buffered against each other by intermediate winding buffers 3, which, due to the water friction, can easily cover most of the space between the poles in order to effectively buffer the windings, as shown in three layers of series-connected windings 4 with a rectangular profile and wound outside each other on a low edge. Along one edge of the windings there extends the water coupling tube 5 with a square profile in good thermal contact with the respective windings and insulated against the adjacent winding layer. Electrical and hydraulic connection can conveniently take place at the end of the machine as indicated for the pole on the left of the figure.
